What's best to clean the cooker and sink unit

[GSX1300R]

What is the best material to clean the cooker and sink unit with. I just want to make sure it keeps its matt appearance. I've tried stainless steel spray but that's no good. Any Ideas please?

Damp, soapy soft cloth. Then dry with another soft cloth.
NO green scourers, or abrasive powders.

I thought about that reply but discounted the idea because Mrs snowy55 reads the forum
